Abstract

The invention discloses an automatic platform leveling device and method. The device comprises a platform, a leveling controller Contrl, a longitudinal inclination sensor QXC, a transverse inclination sensor QXL, and execution mechanisms used for adjusting the inclination state of the platform. The execution mechanisms include the first transverse execution mechanism, the second transverse execution mechanism and the longitudinal execution mechanism. The automatic platform leveling method comprises the steps of calibrating parameters, eliminating the tooth space difference, calculating the adjustment heights of the execution mechanisms, determining the adjustment angle and the rotation direction of a motor of the execution mechanisms, and conducting platform leveling. Due to the facts that the tooth space difference of the execution mechanisms is eliminated, the error that the axes of the inclination sensors are not parallel to the axes of corresponding adjustment mechanisms and the motor is adjusted relative to a reference point O, the influences of the tooth space difference of the execution mechanisms and the error that the axes of the inclination sensors are not parallel to the axes of the corresponding adjustment mechanisms are avoided, repeated adjustment is not needed, platform leveling can be achieved through one-time leveling, and thus the platform leveling efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of measurement and control, and relates to a platform automatic leveling device and method, in particular to a device that can eliminate the influence of backlash difference and solve the problem that the axis of the tilt sensor is not parallel to the axis of the corresponding adjustment mechanism Platform automatic leveling device and method. Background technique [0002] The platform refers to any mechanical device with a certain area. The platform leveling is based on the indication of the tilt sensor installed on the platform, and the adjustment device that can change the platform inclination angle is used to change the inclination angle of the platform, so that the reference plane of the platform is in a horizontal state. [0003] The commonly used levelable platform structure is to install two tilt sensors and three 120-degree adjustment devices orthogonally on the platform. The inclination sens...
